A Case of Malignant Fibrous Histiocytoma of the Pterygopalatine Fossa / 대한이비인후과학회지

ABSTRACT

Although there are some reports of malignant fibrous histiocytoma arising from the head and neck region, there has been no reports on the case originating from pterygopalatine fossa. We experienced a case of 29-year old male patient who visited our hospital with complaints of trismus, periorbital swelling and altered sensation on the left zygomatic area. On physical examination, he showed hypertrophic left middle turbinate, retracted ear drum, and swollen posterior wall of the nasopharynx. On computed tomography, he also showed a low density lesion originating from pterygopalatine fossa. Based on these findings, he was diagnosed with malignant fibrous histiocytoma originating from pterygopalatine fossa. and underwent radical maxillectomy, marginal mandibulectomy, radical neck dissection, and tracheotomy.
